Title:
Internal combustion engine control device
Document Type and Number:
Japanese Patent JP6292135
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the probability of occurrence of smoking of an ignition plug.SOLUTION: A control device sets larger a throttle valve opening degree TA as an accelerator pedal manipulated variable PA is larger, and sets an output increment value Kpower to a value (1+α) larger than 1 when the throttle valve opening degree TA is larger than a predetermined threshold opening degree TAth so as to increase a quantity of fuel supplied to an engine. Note that the control device according to an embodiment sets the throttle valve opening degree TA to an "upper limit opening degree TALmit smaller than the threshold opening degree TAth" and controls the throttle valve opening degree TA so that the throttle valve opening degree TA does not exceed the threshold opening degree TAth when a temperature of the engine is lower than a threshold temperature. As a result, the throttle valve opening degree TA does not exceed the threshold opening degree TAth when the temperature of the engine is low, so that the output increment value Kpower does not become equal to the value (1+α) and the quantity of the fuel supplied to the engine does not increase. Therefore, it is possible to reduce the probability of occurrence of smoking of an ignition plug.SELECTED DRAWING: Figure 4
